Definitions

  • This invention relates to improvements in a lighting unit, and in particular to a fire rated downlight using LED light source technology. It is particularly applicable, but in no way limited, to luminaire components designed to incorporate a sensor arrangement into a downlight, including incorporating a sensor arrangement into or associated with a lens in a downlight Background to the invention
  • LED Downlight fittings or downlighters are a form of lighting unit becoming more and more widely used as light sources in domestic and commercial environments. They offer significant energy savings when compared with traditional incandescent lighting, whilst being particularly neat and unobtrusive in their appearance, since almost the entire downlight fitting is concealed behind a ceiling or other suitable panel or surface, whilst giving out a pleasing light.
  • LED downlights suffer from a number of disadvantages.
  • LED's generate significant amounts of heat. It is important to prevent overheating of the LEDs, and associated control circuitry, since overheating will have obvious detrimental effects on the light output and service life of these components. Indeed, excessive temperatures will cause LEDs and electronic components to fail leading to premature failure of the lighting unit. To this end it is known to provide LED lighting units with cooling means in the form of a heat sink. In addition, there is a consumer driven demand for LED downlights to produce greater and greater amounts of light for a given energy input, so an output of 100 lumens per watt is common today, and this lumen per watt output is expected to rise over time. The result of this trend is that larger and larger heat sinks are required to dissipate the greater amount of heat generated in use.
  • Luminaires including downlights that incorporate sensors are known from GB2526440A. These arrangements are somewhat complex and difficult to incorporate into downlights and relatively expensive to manufacture. It must be appreciated that the market for downlights is very competitive and price sensitive.
  • a luminaire assembly comprising:
  • a light emitting portion comprising a first housing, the first housing comprising a substantially tubular body portion adapted to accommodate a lamp;
  • a driver/control portion comprising a second housing
  • the luminaire assembly further comprising a pluggable connecting cable adapted to form an electrical/data connection between the light emitting portion and the power/control portion, such that the power/control portion and the light emitting portion can be completely separated from each other in a disassembled configuration and attached together in an assembled configuration as and when required;

  • the light emitting portion comprises a collar having a front side and a rear side with an inwardly directed flange on the rear side, a solid state lighting element closing off the rear side of the collar, and a heat sink in direct contact with the solid state lighting element.
  • the collar is made from a material with a melting point above about 900 degrees centigrade, such as mild steel.
  • the solid state lighting element comprises a PCB and preferably the PCB is formed from a material that melts below 900°.
  • the light emitting portion is fire resistant.
  • fire resistant it is meant that the light emitting portion is able to withstand specific temperatures for a specific period of time without failing.
  • Building Regulations in the UK for certain types of buildings require ceilings, and therefore downlights, to withstand temperatures of around 1000° centigrade for a specified period of time.
  • the regulations in other countries may vary in both the temperature and the length of time that the ceiling/fitting must withstand that temperature.
  • One method of achieving this fire resistance is to incorporate intumescent material adapted to expand inside the light emitting portion in the event of a fire and blocking the path of the fire. This provides the required level of fire protection by preventing any fire from getting beyond the light emitting portion.

  • the microphone sensor includes a transmitter antenna for providing audio information to a smart home control system such as Amazon Alexa, Google Assistant, or other verbally controlled home automation systems.
  • the sensor may be connected to a LED display to signify a connection to a smart system.
  • This can be a ring of lights 470 as show in Figure 21.
  • These sensors typically include a PCB and are suitably encapsulated into modules which plug into a socket in the collar region (labelled as socket for 170) in Figure20.
